5. Threesome With Two Men

Women who daydream about the devil's threesome version of this fantasy are often craving some extra attention. "Women enjoy being the sole focus of sex," says Dr. Van Kirk. "It can help them feel goddess like that two men are fawning over them." And really, can you blame them? Depending on the orientation of the parties involved, a MFF threesome may be the safer route to go for women, but it also means sharing the spotlight with another lady. Not so when you're getting your freak on with two dudes.

Having a threesome with two men also offers the opportunity to try certain sex acts that you wouldn't be able to execute in a MFF threesome. For example, double penetration. "Often women who seek double penetration fantasize about the MMF threesome and are excited at the thought of having the full attention of two males to fulfill their wildest desires," says Corrine. Of course, this could be achieved in the MFF version using sex toys. But women who fantasize about this type of threesome are likely craving the real thing.

What Real Women Say:

"I have two platonic, very good looking male friends that I met through a mutual friend when they both relocated to my town for work," says Erin, 25. "The two of them are best friends and are a blast to hang out with -- but we've never taken things to the next level. But in my threesome fantasy, obviously, we go all the way. Together. We're out at the bar we typically meet up at, and as we start drinking, they both start standing closer to me than they usually do, slowly closing in until they're both practically touching me. Both of them start hitting on me in a way that's competitive but not weird, more like in a fun, sexy way where they're letting me know they both want me. So I tell them that they don't have to fight over me, and say we should take things back to my place. Once we get there, it's almost like I don't have to do anything at all. They both tag team the effort, get my clothes off, and take turns going down on me while the other takes their time running their tongue over my nipples and touching me everywhere else. The bigger one penetrates me while the other does it from behind, and it's the most incredible visual. One of these days I'm going to make a move on those two -- I think they'd be into it."
